BICYCLE FORK-CROWN.

SPECIFICATION forming part of Letters Patent N0. 659,187, dated October 2,1900. Application filed July 16, 1900. Serial No. 23,853. (No model.)

To all whom it may concern.-

Be it known that I, HENRY L. F. TREBERT, of Syracuse, in the county of Onondaga, in the State of New York, have inventednew and useful Improvements in Bicycle Fork- Orowns, of which the following, faken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention is a strong, simple, and economical fork-crown in which the 'parts are strongly reinforced, securely locked in position, and easily reached forbrazing.

My invention will be understood by reference to the accompanying drawings, in which the same reference-numerals indicate the same parts in all the figures.

Figure I shows my new form of fork-crown partially in elevation and partially in vertical section. Fig. II is a'plan of the detached finishing-plate. Fig. III is a plan of the crownplate detached. Fig. IVis a plan of the lower or locking plate. Fig. Vis a horizontal crosssection on line V Vof Fig. I, showing the relation of this locking-plateto the fork side and locking-piece.R Fig. VI is an elevation of the inner face of the upper end of a fork side. Fig. VII is a corresponding elevation of the locking-piece.

In the figures, l indicates the steering-post; 2, a tubular reinforcing-piece arranged on the exterior thereof and taking the place both of the reinforcement commonly inserted in the interior and of the outside nishing-ferrule.

3 is the crown-plate, perforated at 4 to fit over this reinforcing-piece and at 5 5 to receive the upper ends of the fork sides 6 6,

slotted at 7 7 to receive the lips 8 8 of the lower or locking plate 9, perforated at 10 to receive the lower end of the steering-post and reinforcing-piece, and having its ends fitting within fork sides, as best shown in Fig. VI. These are slotted at l1 11 and provided with tips l2 l2, respectively, to receive the inner edges 13 13 and to iit the outer slot 14 of the locking-piece 15, formed to fit the upper end of the fork side. This locking-piece is set in position after the other parts are assembled, locking them securely in position and reinforcing the upper ends of the fork sides. The parts are then securely and easily brazed,

the steering-post, an exterior reinforcingpiece fitted to the lower end thereof, a crownplate fitted thereto and ,perforated at its ends to receive the forli sides, the fork sides slotted on their inner faces, a locking-plate fitted to said slots and to the lower ends of the post and locking-pieces fitted within the fork sides and engaging with the ends of said lockingplates.

2. In combination in a bicycle fork-crown, the steering-post, a tubular exterior reinforcing-piece fitted to the lower end thereof, a crown-plate centrally perforated to fit over the reinforcingpiece, and perforated at the ends to receive the fork sides, the fork sides slotted on their inner faces, a locking-plate having lips fitted to said slots and formed with inclined slot-s between the lips and the main portion of the locking-plate, tips on the ends of said lips, locking-pieces fitting within the upper end of the fork sides and formed with slots on their outer faces to receive said locking-plate tips.

3. In combination in a bicycle fork-crown, the steering-post, a tubular exterior reinforcing-piece fitted to the lower end thereof, a crown-plate centrally perforated to fit over the reinforcing-piece, and perforated at its ends to receive the fork sides, the fork sides slotted on their inner faces, a locking-plate having lips fitted to said slots and formed with inclined slots between each lip and the main portion of the locking-plate, tips on the ends of said lips, locking-pieces fitting within the upper end of the fork sides and formed with slots on their inner faces having edges to fit said locking-plate slots and with slot-s on their outer faces to receive said locking- IOO tips, and a nishing-plate having an integral cone to surround the steering-post and with a marginal flange to cover the top plate.

4. In combination in abicycle fork-crown, the steering-post, a crown-plate fitted to the lower end thereof and fitted to receive at its ends the upper ends of the fork sides, the fork sides fitted thereto and slotted on their inner faces, a locking-plate arranged below and parallel to the crown-plate, fitting the lower end of the steering-post and having ends fitted to the slots in the fork sides.

5. In combination in abicycle fork-crown, the steeringpost, a tubular reinforcing-piece fitted outside itslower end and having a beveled upper, end, a crownplate centrally perforated snugly to fit said reinforcing-piece and perforated at its ends to receive the fork sides, the fork sides having their upper ends tting said perforations and slotted on their inner faces substantially on a plane with the lower end of the steering-post, a lockingplate substantially perforated to fit the lower Afinishing-plate formed with an integral cone surrounding the steering-post and reinforcing-piece and With a downwardly-depending marginal flange to cover the top plate.

In testimony whereof I have hereunto signed my naine.
